Disconnect the oil and temp lines. The oil line should have a disconnect location about a foot from the fire wall. The temp line, remove from the block. There will be mounting screws along the top and on the ends. Probably one brace in the middle. Disconnect the radio antenna, it just pulls out. The steering post had two long bolts, remove those. Your might need to remove the radio first. It usually has a brace to the firewall.
Once the dash is loose, then check for the remaining things. I removed my seats put an old sleeping bag and a pillow on the floor, then lying comfortably, I went searching with a good flashlight.
When you're done, take a good shower. That dust is NASTY stuff! Good luck. I'm just a few days ahead of you.
